At what point do food service staff also have to play epidemiologist?

Scott James of The Bay Citizen writes that San Francisco’s Italian eatery Delfina has been considered one of the Bay Area’s best restaurants for more than a decade; Craig Stoll, its co-owner and chef, won a coveted James Beard award in 2008.

But in December, its many accolades could not protect Delfina from an unusual incident. On a night the restaurant was booked solely for a private party, about two dozen patrons were sickened by food poisoning.

The staff determined what each victim ate, and since a vegetarian was among those sickened, oysters, beef tartar and other foods were eliminated as the sources of illness.

“We narrowed things down to the most common denominator,” Stoll said. Their conclusion: Tainted produce, most likely salad greens.

The restaurant contacted its suppliers, but no alert went out to the public, and there was no government investigation. The San Francisco Department of Public Health had not heard of the incident until contacted by The Bay Citizen.

In what appears to be a gap in the food supply safety net, there is no requirement for restaurants to report when their diners are affected by foodborne illnesses even when large numbers of people get sick.

“They are not obligated to report it,” said Richard Lee, director of environmental health regulatory programs for the city.

Mandatory reporting is not required at the state level either, according to the California Department of Public Health. Under both state and local laws, reporting is required only when restaurant workers become sick.

Rajiv Bhatia, the city’s director of environmental health, said the Delfina incident was now under investigation, but added that it was highly unusual for health officials to be unaware of a case involving so many diners.

He suggested a need for stricter rules. “I believe that reporting of potential outbreaks should be mandatory for supermarkets, restaurants, schools and workplace cafeterias, even though this is not a requirement under current law,” he said.

At Delfina, which consistently achieves high scores on health inspections, Stoll said there had not been an illness before or since that night, but he wants the mystery solved.

I prefer peer-review before press releases.

I prefer to bike to the grocery store with my kid in the trailer and dog on the leash – and put the groceries in my knapsack. With daytime highs of 100F, that ain’t happening so much at the moment.

A new report issued today by the University of Arizona and Loma Linda University in California says those reusable grocery bags can be a breeding ground for dangerous foodborne bacteria and pose a serious risk to public health.

Maybe.

Maybe it’s Gotcha microbiology where a bug is found, but the public health significance isn’t matched up with epidemiology (where are the sick people).

Chapman has highlighted the flaws in the paucity of data that is out there, and will be going through this later tonight.

The American Chemistry Council, which underwrote the research project, may be a fine organization – and I’m all for industry sponsoring research – but why not release the results in a peer-reviewed journal?
 

It’s Groundhog Day again for the Brits who once again have a report that public health types were too clueless about their jobs so a whole bunch of people became unnecessarily sick with E. coli O157.

Scotland, 1996. Wales, 2005. Now this. At least Prof. Hugh Pennington didn’t have to do the same report again.

Don’t eat poop, and if you do, make sure it’s cooked.

Raw animal feces usually are not cooked when children go play with them at petting zoos.

A report into Britain's largest outbreak of E. coli O157 at an open farm last year concluded it could have been avoided if visitors had been kept away from animal feces.

Duh.

The outbreak, which affected 93 people mostly children, was made worse by the slow reaction of health authorities before the petting farm in Surrey was closed, the investigation found.

Only 33 people would have fallen victim to the infection had authorities acted sooner, it said.

Eight of the children infected required dialysis and some have been left with permanent kidney damage. At one point during the outbreak last August and September victims were occupying all the children's acute renal support services in London.

A number of families of affected children are preparing to take legal action against the farm.

In a 250-page report, the investigation said an outbreak control team of officials from local councils, medical authorities and the Health Protection Agency (HPA) had convened "exceptionally late."

It made 43 recommendations but said it did not want to ban petting farms. It said there should be a code of practice to ensure farms kept visitors away from animal fecal matter.

In addition it said the public should be educated about the dangers of E.coli O157 and how its risks could be minimized by careful handwashing, particularly for young children.

No, no one wants to be educated, especially in British schools. But some of the government agencies and food providers could provide compelling and current, food safety information rather than the piping hot bullshit currently coming out of the U.K. Food Standards Agency and others who appear delusional about what can happen.

Again:

Eight of the children infected required dialysis and some have been left with permanent kidney damage. At one point during the outbreak last August and September victims were occupying all the children's acute renal support services in London.

Professor George Griffin, who led the investigation, said,

"This outbreak could very likely have been avoided if more attention had been given to preventing visitors being exposed to animal fecal matter. Once it had started, there is no doubt that even with prompt action this would have been a big outbreak. Nevertheless there was a lack of public health leadership by the Health Protection Agency and a missed opportunity to exercise decisive public health action and thereby restrict the size of the outbreak."
